Qiming Venture Partners’ Post

MEDx, a portfolio company of Qiming Venture Partners, played a key role in a recent clinical study published in The Lancet Oncology. The study focuses on CMG901, a novel targeted Claudin 18.2 (CLDN18.2) antibody-drug conjugate. MEDx provided critical CLDN18.2 antibody reagents and biomarker testing services, supporting the trial's success and advancing precision treatments for gastric cancer. This study is a multi-center, open-label, single-arm Phase 1 trial (KYM901) that assessed the antitumor activity and safety of CMG901 in patients with advanced gastric cancer or gastroesophageal junction cancer. MEDx's central laboratory played a pivotal role in testing CLDN18.2 expression levels during the trial. In the dose escalation phase, tumor samples were retrospectively analyzed for CLDN18.2 expression. Patients whose tumors showed a membrane staining intensity of at least 2+ and expression in at least 5% of tumor cells were included in the dose expansion phase. This approach lays a solid foundation for precision screening and future treatment optimization. #PrecisionOncology #ClinicalResearch #GastricCancer #Biomarkers #HealthcareInnovation #TargetedTherapy #Claudin18.2 #QimingPortfolio #QimingHealthcare
